IMPORTANT NOTE for customers who created an account prior to June 12, 2006: Significant improvements have been made to BlackBerry Internet Service with the introduction of BIS 2.4. Existing users who have not migrated to BIS 2.4 will be prompted with a migration option after you enter your user ID and password. Read and understand the changes before making a decision. Select "Yes" if you wish to migrate, or "No" if you wish to continue to use your existing service. After you upgrade to BlackBerry Internet Service 2.4, you will not be able to revert to the previous version.


We recommend that you upgrade to take advantage of new BIS 2.4 features including push (vs. polled) email synchronization, multiple "sent from" email addresses, individual email account icons, and support for uploading attachments.
